Why is a cell-mediated immune response more effective against intracellular microorganisms (such as viruses) than an antibody-mediated response?
A) Cell-mediated (vs. antibody-mediated) response results in activation of a many more immune cells, so it is more effective at destroying antigens
B) Intracellular microorganisms are too large for antibodies to be effective against
C) Intracellular microorganisms are too small for antibodies to be effective against
D) Cell-mediated response results in destruction of cell containing the intracellular microorganism; antibodies can't enter cells
